COMBINED ANNUNCIATOR AND FIRE-ALARM.

SPECIFICATION formingpart of Letters Patent No. 563,269, dated July '7,1896.

Application filed September 27, 1894. Serial No. 524,819. (No model.)

To all whom it may concern;

Be it known that I, MANIOUS GARL, a citizen of the United States,residing at Akron, in the county of Summit and State of Ohio, haveinvented certain new and useful Improvements in a Combined Annunciatorand Fire-Alarm; and I do hereby declare that the following is a full,clear, and exact description of the same, reference being had to theannexed drawings, making a part of this specification, and to theletters of reference marked thereon,'in which- Figure 1 is a viewshowing the back of the frame removed and illustrating the arrangementof the difierent parts, and also showing the manner of connecting thedifferent wires. Fig. 2 is a view showing a portionof the frame andillustrating the position of the different magnets, except theindicating magnets, which are removed. Fig. 3 is'a view showing thefire-alarm armature and manner of connecting the bar and post. Fig. 4 isa view showing the outer end of the setting-arm,

also showing the plate for adjusting the upward movement of the outerend of the setting-arm. ,Fig. 5 is a view of the setting-arm, showingthe same properly pivoted and pro vided with its armature. Fig. 6 is asectional view of the plate, return-call push-button, and the fire-alarmspring. Fig. 7 is a diagrammatic view showing a portion of the mechanismand the circuit connections.

The present invention has relation to combined annunciators andfire-alarms; and it consists in the difierent parts and combination ofparts hereinafter described, and particularly pointed out in the claims.

Similar letters of reference indicate corresponding parts in all of thefigures of the drawings.

In the accompanying drawings, 1A represents the frame, which isconstructed in the ordinary manner, reference being had to properlyattaching the different parts hereinafter described, and is of a size tocorrespond with the numbers designed to be placed in the frame.

The bell-magnets B are constructed in the ordinary manner and arearranged substantially as illustrated in Figs. 1 and 2. The

magnets 13 are provided with the armature a, which operates upon the adjusting-post b and its different parts in the ordinary manner.

From battery A leads the wire a, which wire is extended to and connectedwith the plate a, which plate is connected with and to the post I),which post is connected to one of the lift ing-magnets O, the otherlifting-magnet 0 being connected to the plate D, which plate is providedwith the indicating-magnets E, which indicating-magnets are eachprovided with ordinary return=wires.

To make a call, the push-button d is'opei ated in the ordinary manner,which connects the lifting-magnet O and elevates the armature G, whicharmature is provided with the extended arm 6, the inner end of which armis insulated and loosely attached to the top or upper end of theindicator-replacing bar or slide H by means of the pin e or itsequivalent. The indicator-replacing bar or slide is held in properposition by means of the posts f, which posts are connected with theplate D in any convenient and well-known manner.

The armature G is located below the liftingmagnets C, substantially asillustrated in Fig. 2, and, as shown in Fig. 5, it is pivotally attachedto the yoke g by means of the setscrews 9, which set-screws are attachedto the yoke g, said yoke being attached to the frame A.

The armature G is provided with the arm h, which arm extends through theframe, and its outer end is provided with the weighted knob h, whichknob serves as a counterbalance for the armature G and its differentparts, said weighted knob h and the arm 71 together being somewhatlighter than the armature G and its parts, by-Which arrangement thearmature G and its parts will fall by gravity, and by reason of thecounterbalance will be easily lifted, thereby saving battery power. 7

When it is desired to bring all of the indicators to their normalposition by hand or in the ordinary manner, the knob h is forceddownward, thereby elevatingthe slide H and its difierent parts, whichmovement brings the indicators to their normal position, as hereinafterdescribed.

It will be understood that the knob 'his not intended to be operated byhand, except when all of the indicators are to be put back to theirnormal position, for the reason that the indicators are resetautomatically and the last call is only indicated. By my peculiar mannerof connecting the magnets C and E said magnets will act in unison when acall is made, thereby lifting the armature G and the bar Hsimultaneously, which replaces the indicator acted upon by the call justbefore the last. As the armature G is lifted the spring is is broughtinto contact with the post 7a, which connects the bell-m agnet l3, andrings the call-bell and shunts the magnets O and E. After the call ismade or the current broken the armature Gr, together with its arm e andthe slide H, falls and permits the respective gravity-arm K to assumesubstantially a horizontal position, as indicated in Fig. 1, whichbrings the proper indicatorarm K into proper position to indicate theplace from which the last call is made.

For the purpose of providing a means for a return call to answer a callthat has been made, push-buttons L are provided, which are located atthe bottom or lower portion of the frame A, the return-call push-buttoncorresponding in number with the indicator-magnets, thereby providing areturn call for each place from which a call is made. The pushbuttons Lare extended through the plate L and into the sockets L within whichsockets are located springs L which springs are for the purpose ofnormally holding the springs L out of contact with the posts L saidposts L being connected to the various call-bells by the wires a.

For the purpose of providing a means for ringing all of the call-bellsat one time in the event of fire, the pull-bar B is provided,whichpull-bar extends through the case A and is provided with the knob Bwhich knob is pulled outward, thereby bringing the crosspins (3 intocontact with the springs CZwhich springs are attached to the posts Lsubstantially as illustrated in Fig. 6, said springs being so locatedthat they will normally be out of contact with the pins 0, but when thebar B is pulled outward all of the cross-pins C will be brought intocontact with the springs C thereby ringing all of the call-bells.

For the purpose of holding the pull-bar B in proper position, thecross-bar D is provided, which cross-bar slides back and forth on thebars D For the purpose of automatically turning in a fire-alarm thevarious rooms are provided with thermostats D which thermostats areproperly connected to a battery and to the fire-alarm magnet D and whenthe current is connected by the action of a thermostat to the magnets Dthe armature D will be drawn against said magnet, thereby automaticallybringing into contact the pins .0 with the springs 0 and for the purposeof increasing battery power in case a large number of pins 0 are to beoperated upon additional batteries may be employed.

For the purpose of connecting the plate L with the wire a, the wire a.is provided,which wire, together with the wire a, is attached to thescrew a. The wire a is fed from the bar 0, this connection beingarranged substantially as illustrated in Fig. 1.

For the purpose of providing additional battery power for thefire-alarm, the spring M is provided, said spring being automaticallyconnected by means of the screw M com ing in contact with said spring,after the bar B has been moved toward the magnet D which spring isconnected to the auxiliary battery A by means of the wire l then throughthe fire-alarm magnets D onto the post N", then through the thermostat Dby means of the wire N and returning is attached to the battery-wire atX.

For the purpose of elevating the gravity arms K, after they havedropped, the sliding bar H is provided with the cross-arms b,whichcross-arms are bent laterally at their upper ends, as illustrated inFig. 2, so that they will properly engage the gravity-arms K.

It will be understood that each of the mag nets E are to be providedwith armatures, such as W, so that when the armatures are lifted theywill permit the gravity-arms to fall.
